UNITED STATES PATENT OFFICE.

JOHN A. BOWEN, OF SALT LAKE CITY, UTAH.

BELT-CLEANER.

To all whom it may concern:

Be it known that I, J OHN A. BOWEN, citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new and useful Improvements inBelt-Cleaners; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in belt cleaners, andparticularly to belt cleaners for concentrating machines, and has for anobject the provision of means that will automatically and continuouslyclean the belt and be susceptible of adjustment toward and from the beltand laterally in respect thereto at all times.

Another object of the invention is the provision of a belt cleanerarranged to clean the same during the movement of the belt in operationand broadly similar to applicants co-pending application #lt5,620, filedJuly 27, 1908.

A further object of the invention is the provision of a belt cleanerthat has a specified point for cleaning the belt as the same moves anddischarging the matter removed from the belt at a particular point.

lVith these and other objects in view the invention comprises certainnovel constructions, combinations and arrangement of parts as will behereinafter more fully described and claimed.

Inthe accompanying drawings: Figure 1 is a top plan view of my improvedbelt cleaner, certain parts being broken away to better disclose theconstruction. Fig. 2 is an end view of the structure shown in Fig. 1.Fig. 8 is a bottom plan view of the structure shown in Fig. 2. Fig. 4 isan end view of my improved belt cleaner shown in position and inconnection with a belt. Fig. 5 is a plan view of a slightly modifiedform of brush carrying bar. Fig. 6 is an end view of Fig. 5.

In concentrating machines that use moving belts it is very desirable tocontinuously move the belt and to have means that will clean the beltduring its movement so as to present a clean belt to the new matter tobe concentrated. My improved belt cleaner is adapted to be used inconnection with concentrating machines and will accomplish the abovedesirable result suggested and not Specification of Letters Patent.

Application filed September 8, 1908.

Patented Got. 12, 1909.

Serial No. 452,023.

only clean the belt but deposit the matter removed from the belt at aparticular place from which it may be carried or removed to any desiredplace.

In the accompanying drawings I have disclosed an embodiment of myinvention in which indicates a belt upon which is concentrating anydesired material and which is adapted to pass around rollers is, Z and mat one end and at the other end around suitable rollers not shown. Theposition of the roller causes the material or matter washed during theconcentrating period to be projected from the belt as the same beginsits return movement and the rollers Z and mcause the belt to travel at aconsiderable angle, preferably at a 45 degree angle past the brush 2'which is adapted to remove all of the matter clinging to the belt and todeposit the same substantially directly below the point at which thebrush engages the belt. Fig. & shows a preferred arrangement but someother arrangement could be used within the spirit of the invention, themain feature being the way the brush i is caused to engage the belt andthe various means for supporting and manipulating the brush.

The brush 2' may be of any desired kind and is arranged to be secured byany desired means as screws i to a cross bar 6 which may be hollow orsolid as most desirable but formed with reduced ends or mandrels Z) andZ)". The ends I) and b are squared or formed with flat sides forengaging thimbles or sleeves e, e which are provided with suitableflanges f, f. The sleeves or thimbles c, e are adapted to fit thereduced ends of bar 2), and also to have two faces of their outersurfaces engage the sides of opening 72. in the supporting brackets a, aso as to permit a free sliding movement of the sleeves in the slot underthe action of set screws 0, c and yet be prevented from turning so as toalways hold the brush 2' at a proper angle in respect to belt j. Thesleeves e, e are provided with set screws (Z, cl that engage the ends ofthe reduced portions 6 and b" and are turned until the ends of the setscrews have engaged the ends of the reduced portions of bar Z) and alsothe flanges f, f have engaged the brackets a, a. After the sleeves andbar 6 have taken this position bar I) may be adjusted' longitudinally ortransversely of the belt j by loosening up on one of the set screws (Zand tightening up on the other.

The respective sleeves e, e are engaged by set screws 0, 0 so as to pushthe same transversely along slots 71, for adjusting the brush 2' towardor from belt j. It will be observed that the set screws 0, 0 simplyforce the brush 6 toward the belt and in order to relieve any pressureof the brush against the belt set screws 0, 0 must be turned in areverse direction.

In mounting the belt cleaner the belt j is preferably caused to passaround roller 70 so as to discharge water and dirt at that point and tothen cause the belt j to move downward around the roller l for causingthe same to pass brush 2' at a considerable angle. The brush 2' is thensecured to bar 1) and bar I) secured in brackets a, a as heretofore setforth. The brackets a, a are then mounted upon supports a, n positionedon each side of the belt j by means of U shaped bolts 0 passing throughslots 9 and apertures p. By the use of U shaped bolts 0 and slots 9 thebrackets may be supported at any desired place upon support a and thesupport a may be of varying sizes, the slot 9 accommodating thespreading of the bolt 0 in case of increase in size of support n. Afterthe brackets have been properly secured to their supports a the setscrews 0, c are adjusted for supporting the brushes 2' against the beltand by this construction the brushes may be pressed against the belt jto any desired extent for removing matter therefrom. Also it will beobserved that the pressure of the brush 2' against the belt may bevaried as occasion may require and consequently save the wear upon thebrush and belt, a heavy aressure being used when the matter sticksclosely to the belt and a light pressure being used when the adhesion tothe belt is only light.

In Figs 5 and 6 will be seen a slightly modified form of bar '1" whichmay be used in place of bar 7). The bar 1" is made in the form of an Ibeam and has secured to the ends thereof blocks or mandrels r and 1"which are adapted to take the place of reduced portions 6 and b whichwhen used fit into the sleeves e, e. The blocks 1" and 0 may be of anydesired length for accommodating the length of the sleeves e, c and itwill be of course evident that the sleeves e, 6 may be of any desiredlength for permitting any desired amount of lateral adjustment of thebrush in regard to the belt. The bar 1* is provided with any desirednumber of apertures through which the securing screws 2" may pass insecuring the brush 2' in place.

My improvement in belt cleaners has been specifically set forth inregard to cleaning belts for concentrators, but it will be evident thatthe same will be of equal advantage in cleaning belts for otherpurposes. The means for clamping the supporting brackets in place andalso the means for adjusting the brush transversely in respect to thebelt and toward and from the same presents a device that is adapted tocause the brush to exert the proper pressure against the belt at theproper place for cleaning the same regardless of what kind of a belt isbeing cleaned. In case one brush is not sufiicient for thoroughlycleaning any particular belt a second brush could be used which would besimply a duplication of the showing disclosed in Fig. 4.

WVhat I claim is:

1. In a device of the class described, the combination with a brush, ofspaced uprights, brackets adapted to be adjusted vertically upon theuprights, and provided with inclined slots, sleeves inserted through theslots, flanges formed upon the inner eXtremities of the sleevespositioned to bear against the brackets, a mandrel inserted within thesleeves for supporting said brush, and tension means inserted throughthe sleeves and bearing against the mandrel.

2. In a device of the class described, the combination with a brush, ofspaced uprights, brackets adjustable vertically upon the uprights, meansadapted to permit horizontal adjustment of the brackets relative to thestandards, said brackets being provided with inclined slots, sleeveseach having a flange at one end inserted through the slots with theflanges in engagement with the brackets, a mandrel for supporting saidbrush having its opposite ends inserted within the sleeves, and tensionmeans inserted through the brackets and bearing upon the ends of themandrels, and positioned to bind the flanges in engagement with thebrackets.

In testimony whereof I aflix my signature.

in presence of two witnesses.
